Are theists by nature simply insecure?

[Kyuuketsuki]

But there is evidence that there may be a why. And evidence that there may be no why at all. So the choice to believe is not for lack of evidence

I was under the impression that there was no evidence at all for a reason why the universe exists (I suppose that's what we're talking about here) ... what evidence are you aware of that indicates the existence of a god? Obviously when I refer to "evidence" I mean evidence that is validatable and cannot be more reasonably interpreted otherwise or as an open question.
